We study social determinants of health and how to achieve health equity. Social determinants of health at the levels of society and community include income inequality, economic crises, and social capital; and those at individual level include income, educational attainment, occupation, and interpersonal relationships. We have also conducted intervention studies aiming to achieve health equity in the community.
